Ahoy! If you're looking for a simple, powerful solution for high performance boating, then these marine D.U.I. (Davis Unified Ignition) distributors from Performance Distributors are the answer. These virtually waterproof and vibration-proof distributors are easy drop-in units with one-wire hookup. There are no wiring hazards to leave you adrift and no hassles! The electronic Dyna-Module and high-voltage coil are built inside of the distributors and produce a longer spark duration, allowing you to widen your plug gap and get a more complete fuel burn. Marine D.U.I. distributors are available in performance versions that crank up to 7,000 rpm and racing versions at 10,000 rpm. D.U.I. distributors are calibrated by machine to dial-in the smoothest advance curve for your application. They are hand-assembled, polished, lubed, and checked for exact tolerances, and the housings are drilled with flame arrestor holes. All of these features allow you to navigate with instant throttle response and more power. Whether you're taking a leisurely ride around the lakes, offshore cruising, or running the waves, anchor your boat with high performance marine D.U.I. (Davis Unified Ignition) distributors from Performance Distributors.

Nice improvement

Simple to install. Put this dizzy in and swapped the 2bbl Rochester to 2bbl Holley. Made a good deal more power over the old stock 350 in a heavy cabin cruiser.
